I DRINK YOUR BLOOD

Horace Bones, the leader of a Manson-like cult of hippies, conducts a Satanic ritual in the woods. Local girl Sylvia, who has befriended cult member Andy, secretly observes the ritual. Sylvia is seen by the cult and flees, but is caught and raped by several of the cultists. Sylvia emerges from the woods the next morning, beaten and traumatized. She is found by her younger brother Pete and Mildred, who runs the local bakery. They return Sylvia to her grandfather, Doc Banner. Mildred seeks help from her boyfriend Roger Davis, leader of a construction crew working on a nearby dam. The cult members' van breaks down, forcing them to remain in the town. They buy pies from Mildred, who explains that, as most of the town is deserted and awaiting demolition, they can stay in any vacant building they wish.

Learning of the assault on Sylvia, Banner confronts the cult, but they assault him and force him to take LSD. Horace initially wants to kill Banner, however, Pete and cult member Sue-Lin intervene and Banner is released. Enraged by the incident, Pete takes a shotgun to get revenge but encounters and kills a rabid dog. Pete takes some of the dead dog's blood, then injects it into meat pies at the bakery and sells them to the cult members. After eating the contaminated pies, the cultists begin to showing signs of infection and lapse into violent behavior.

One of the cultists panics and runs into the night. She is picked up by construction workers sent by Roger to investigate. She parties with the group and has sex with some of them, before showing signs of infection. Molly also absconds with Carrie, another cult member. Two construction workers investigate the house occupied by the cultists, and Horace kills them.

Andy and Sylvia, who have made peace, are discovered at the Banner house by Pete, who admits what he has done. Meanwhile, Banner has reported the potential rabies epidemic and is joined by Dr. Oakes, the town doctor. Banner, Oakes, and Roger soon discover that the entire construction crew is infected with rabies, and are pursued by the mob until they reach a water-filled quarry, which frightens the attackers off.

Molly and Carrie emerge from the woods and are taken in by a concerned homeowner. Carrie soon begins showing signs of being infected and attacks the homeowner with a knife.

Andy helps Sylvia and Pete escape after they discover Banner dead in the barn, impaled on a pitchfork. They encounter Molly, who commits suicide after learning that she has rabies. Horace encounters Sue-Lin, but she escapes his attempt to kill her by committing suicide via immolation. Horace and Sue-Lin loyalist Rollo engage in a fight, allowing Andy, Sylvia, and Pete to escape. Rollo soon gains the upper hand and impales Horace with a sword. Andy, Sylvia, and Pete encounter Mildred, who has barricaded herself in the bakery. As Mildred opens the barricade, Andy is killed by one of the rabid construction workers. Sylvia and Pete retreat with Mildred to the basement, with one of the rabid townsfolk managing to get through, where he is subsequently killed by Mildred. The group leaves the bakery to escape in Mildred's car, but crowds of the rabid cultists and the townsfolk converge on them, overturning the car. Oakes arrives with reinforcements and guns down the infected. Mildred, Sylvia, and Pete then emerge from the car, shaken but otherwise unharmed.

After a wave of rabies-induced violence decimates the cult and construction crew, the surviving townspeople barricade themselves as the infected close in. The film ends with the survivors' fate uncertain as the rabid attackers surround them.

The ending embodies the nihilism and chaos of exploitation cinema, offering little comfort or resolution. By leaving the survivors trapped with the threat still looming, the film underscores its grim take on both revenge and contagion, suggesting that violence—once unleashed—is impossible to fully contain.
